The AD7175-8 is a low noise, fast settling, multiplexed, 8-/16- channel (fully/pseudo differential) Σ-Δ analog-to-digital converter (ADC) for low bandwidth inputs. It has a maximum channel scan rate of 50 kSPS (20 ìs) for fully settled data. The output data rates range from 5 SPS to 250 kSPS.
The AD7175-8 integrates key analog and digital signal condition-ing blocks to allow users to configure an individual setup for each analog input channel in use. Each feature can be user selected on a per channel basis. Integrated true rail-to-rail buffers on the analog inputs and external reference inputs provide easy to drive high impedance inputs. The precision 2.5 V low drift (2 ppm/°C) band gap internal reference (with output reference buffer) adds embedded functionality to reduce external component count.
The digital filter allows simultaneous 50 Hz and 60 Hz rejection at a 27.27 SPS output data rate. The user can switch between different filter options according to the demands of each channel in the application. The ADC automatically switches through each selected channel. Further digital processing functions include offset and gain calibration registers, configurable on a per channel basis.
The device operates with a 5 V AVDD1 . AVSS supply, or with ±2.5 V AVDD1/AVSS, and 2.5 V to 5 V AVDD2 and IOVDD supplies. The specified operating temperature range is .40°C to +105°C. The AD7175-8 is available in a 40-lead LFCSP package.
